Graphically it looks like this: It sounds to me like you really should just cut this in HALF with: PHP script outputs header with JavaScript and then body with JavaScript. As you have it now, every page hits the web server *TWICE* causing twice the overhead of resources used by HTTP. That's not real efficient. But that's just me. > 1) the Page calls the header > 2) the header calls > 3) a php generated JavaScript file which calls > 4) a php file that reads the folder on the server and > builds the JavaScript arrays I mean to say: <?php /* Choose your JavaScript banner ads here. */ require 'header.inc'; //This outputs JavaScript to rotate selected banners /* rest of page here */ ?> > Now I need to add a feature and I am bumping my head on this one. > > How do I report the file name of the file that called the header in # 4 ? > In other words, I want the name of #1 to be reported in #4.

You may need to pass it around in a new variable <?php $source_page = $_SERVER['HTTP_REFERER']?> from PHP to JavaScript and back again, but it's there for you to use it. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
